Clinical Evaluation of a Compomer and a Glass Ionomer Cement : 1-Year Follow-Up

Objectives: The aim of this study was to compare clinically a high viscosity glass ionomer cement (GIC) with a compomer at one year.
Methods: Fourty patients (mean age: 6,8±1,08) who referred to Ege University School of Dentistry with at least four carious primary molars participated the study. The test materials were placed as; Group I: Fuji IX GP Extra+ Fuji G-Coat Plus, Group II: Fuji IX GP Extra+ Fuji Varnish, Group III: Dyract Extra+ Fuji G-Coat Plus and Group IV: Dyract Extra. Totally 40 Class I and 168 Class II cavities were restored at baseline and at one-year examination 205 restorations were evaluated and 3 teeth were lost. Two calibrated observers evaluated the restorations using modified Ryge criteria. Pearson Chi Square, Kaplan Meier and long rank tests were used to analyze the survival rates.
Results: There were no failures in Class I cavities of all groups. The survival rates of Class II restorations were 87.6% for Group I, 89.8% for Group II, 97.9% for Group III, 94% for Group IV. However there was no statistically significant difference among the groups after the observation period of one year. In addition the scores of modified Ryge criteria were found similar between the groups.
Conclusions: It could be concluded that high viscosity GIC may be an alternative restorative material to compomers in the restoration of primary molars in children. However, no additional effects of varnish or coat with these materials could be demonstrated.
